Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] see Figure 1 to Figure 2 , a power tool 10, the power tool 10 of the present embodiment is a swinging machine, which includes a housing 11 that is arranged approximately in an angle, and a motor 13 is arranged inside the housing 11, the motor 13 has a motor shaft 18, and the motor bearing 182 supports the motor shaft 18. The bearing 182 can be an ordinary ball bearing, preferably a bearing with low friction and high temperature resistance while providing a very high speed, such as an air bearing, a hydraulic bearing, etc. These bearings use gas or The liquid acts as a lubricant with low resistance, allowing higher rotational speeds while maintaining a low vibration level; less resistance results in less friction, less power loss and less heat generation, resulting in less temperature rise. Of course, not only the motor shaft ...

Abstract

The invention relates to a power tool, which comprises a housing, a motor and a transmission mechanism arranged in the housing, and a working head doing swinging movement relative to the housing under the drive of the motor and the transmission mechanism; and the swinging frequency of the working head is more than or equal to 20000 times/min. The swinging frequency of the working head of the power tool provided by the invention is greatly improved compared with that of the normal power tool, so that the working quality and the working efficiency can be dramatically improved.

Description

technical field [0001] The invention relates to a power tool, especially a swing power tool. Background technique [0002] The common oscillating power tools in the industry have many uses. Its working principle is that the motor drives the output shaft to drive the working head to swing around its axis through the transmission mechanism. When the user installs different accessory working heads on the output shaft, a variety of different Various operating functions, such as sawing, cutting, grinding, scraping, etc., to suit different work needs. [0003] Conventional oscillating power tools currently on the market have a oscillating frequency of the working head at about 15,000 times / min, which is low in oscillating frequency and low in working efficiency. Contents of the invention [0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a power tool with a high swing frequency of the working head. [0005] In order to achi...
